Product details
The CSB XHRL12500W belongs to the XHRL series and is a 12V top terminal Valve Regulated Sealed Lead Acid battery featuring Absorbent Glass Mat (AGM) technology, with a gas recombination efficiency of up to 99% and a maintenance-free design. Compared to the HRL series, this series delivers higher high-rate power, and its officially designated application is data center uninterruptible power supply, suitable for float charge backup power scenarios.
In terms of power, the XHRL12500W at 25°C and 10.02V per cell has a 15-minute rate nominal capacity of 500W; at a final voltage of 1.67 VPC, the 5-minute rate power reaches 912.17 W/cell, and the 15-minute rate power is 502.83 W/cell. The battery's maximum charge current is 50.00 A, maximum discharge current is 1200 (5 seconds), short-circuit current is 3685 A, and internal resistance is 2.22 mΩ. These data indicate that its design focus is on short-duration high-rate discharge.
In terms of dimensions, the battery is 343.0±2.5 mm long, 170.0±2.0 mm wide, and 216.6±2.5 mm high, weighing approximately 36.90 kg. The terminal uses I2 threaded lead alloy, compatible with M6 bolts, with a terminal torque of 51.7±10.3 Kgf∙cm, equivalent to 44.9±9.0 Lbf∙in or 5.1±1.0 N∙m. The case material is PP (UL 94-HB), and a flame-retardant 94-V0 version is available upon request.
Charging and temperature conditions: at 25°C, the float charge voltage is 13.5 to 13.8 Vdc/battery, and the equalize charge voltage is 14.4 to 15.0 Vdc/battery. The nominal operating temperature is 25°C, with a discharge range of -15°C to 50°C, and a charge and storage range of -15°C to 40°C. Regarding self-discharge characteristics, storage at 25°C for 90 days is less than 10%, storage is possible for up to 6 months, and with equalize charge it can be extended to 10 months; the battery must be fully charged before use, and if the storage temperature exceeds 25°C, it should be charged earlier.
In terms of design life, it is 10 years under 25°C float charge backup service, and over 12 years under Eurobat 20°C conditions, belonging to the Very Long Life category. The product is manufactured in accordance with IEC 60896-21/22:2004 and is UL1989 recognized (MH14533). Thanks to its pure lead construction and proprietary formulation, the XHRL12500W is well-suited for applications such as data center UPS that require high-rate output and long-term float charge backup.
